hi I am currently using an old version of iinets bob to connect to the internet and make phone calls. My mate told me that i should upgrade to the ASUS DSL-N55U ADSL2+ Modem/Gigabit Router/Dual Band Wireless-N so i can get 5 Ghz instead of the current 2.5 is there a way I can run this where it doesn't interfere with my new modems speed???
